Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | N.C. | unconnected | Listed as N.C. (no connection) in the pin connections diagram; the datasheet states no function for this pin. |
| 2 | Logic Input A | input | Inverting logic input with about 170 mV of hysteresis around a 1.67 V threshold, accepting signals from ground to VCC and carrying an internal 30 kΩ pulldown. |
| 3 | GND | power_in | Ground reference pin for the driver and the common return for the drive outputs. |
| 4 | Logic Input B | input | Inverting logic input with about 170 mV of hysteresis around a 1.67 V threshold, accepting signals from ground to VCC and carrying an internal 30 kΩ pulldown. |
| 5 | Drive Output B | output | Totem-pole drive output that sources and sinks up to 1.5 A, with a 100 kΩ pulldown holding the gate low when VCC is below 1.4 V. |
| 6 | VCC | power_in | Supply pin with an operating range of 6.5 V to 18 V and a maximum device rating of 20 V. |
| 7 | Drive Output A | output | Totem-pole drive output that sources and sinks up to 1.5 A, with a 100 kΩ pulldown holding the gate low when VCC is below 1.4 V. |
| 8 | N.C. | unconnected | Listed as N.C. (no connection) in the pin connections diagram; the datasheet states no function for this pin. |
